    In Mr. Birks' basement, there were 2 cracks on the walls of his foundation. When it rained or simply when he turned on his garden hose, water would pass through these cracks and create water infiltration inside. Our client wanted to finish his basement and in order to do that he had to repair these cracks. He therefore contacted Systèmes Sous-sol Québec for a quick solution to eliminate this water infiltration.

     Our experts started by injecting polyurethane into the cracks. This resin goes deep into the cracked wall, unlike methods that simply repair the surface, and goes down to the ground outside. Following the injection, they installed our FlexiSpan wall crack repair system to stop water from coming in.

     

    Polyurethane injection combined with FlexiSpan is a permanent solution to keep wall cracks dry.

    The foundation of Mr. Diaz's house was slowly sagging. He knew that if he does nothing, his foundation will continue to sag. So he wanted to have it fixed before the problem gets worse. He decided to contact Système Sous-sol Québec to obtain a permanent solution.

    The problem was that the ground under the foundation is weak and unstable. This caused movement of the wooden beams which support the weight of the house causing overload of weight and slits in the beams in several places. Because of this, the foundation was quietly sagging.

    The solution for our client is to install SmartJack supports to support the joist reinforcement device in place. A hole is dug in the earth for each SmartJack installed and is filled with compacted fill to create a stable base. About ten brackets were installed in order to support the weight evenly and straighten the floor to the floor above in its initial position.

     With this solution, Mr. Diaz will have nothing more to fear for his foundation.
